Weighed salts Y and Z were left exposed in the laboratory overnight. In the morning Y had gained weight, and Z had become liquid. What conclusion could be drawn about the nature of the two salts?
Z is efflorescent
Y and Z are efflorescent
Y and Z are deliquescent
Y and Z are hygroscopic
Y is deliquescent

the answer is wrong. Note that all deliquescent are hygroscopic, but not all hygroscopic are deliquescent. Hygroscopic is when a salt absorbed water from the atmosphere and become moist but does not become solution. But deliquescent is when a salt absorbs water from the atmosphere and becomes a solution.
corrections should be made
in dis ques, Y absorbs moisture but didn't dissolve in it ro form a solution therefore hygroscopic,
Z absorbs and dissolve to form solution therefore deliquescent.
note all deliquescent substance are hygroscopic but not not all hygroscopic are deliquescent.
D is d answer
I think D is the correct answer cuz if u say deliquescent, dat mean u are ignoring "y" which is hygroscopic and also remeber that a deliquescent substance can also be a hygroscopic while a hygroscopic sub. can't be deliquescent
Myschool pls note that all deliquescent substances are hygroscopic and not all hygroscopic substances are deliquescent
So the correct option is option D
Reference new school chemistry
Deliquescent absorb moisture from the atmosphere and eventually turns into liquid but hygroscopic absorb moisture and will only gain weight. So option
Deliquescent absorb moisture and eventually turns into liquid or semi liquid and hydroscopic never turned liquid but will only gain weight
With respect to all other options they are correct coz Y can either be deliquescent or hygroschopic and Z is difinately deliquescent
myschool D is correct because
Both draw water from the atmosphere hence are hygroscopic,in addition Z forms solution with the water drawn(deliquence)
Recall that
**All Deliquecent substances are hygroscopic but not all hygroscopic substances ade deliquescent.**
I am surprised this has not been corrected. The correct answer is D. Deliquescent substances are hygroscopic but not vice-versa. This question has been explained in Lamlad Chemistry page 13, No 56 and page 17 no. 54
